Risk of Anemia after Gastric Bypass Surgery
It is common protocol to correct any deficiency or low vitamin and mineral levels before bariatric surgery. Iron deficiency is included in this protocol.
However, Anemia is still a common complication of Gastric Bypass Surgery, particularly in women. For women who are postmenopausal, the likelihood of becoming anemic after receiving gastric bypass surgery is more than 50%.
Although women are at a higher risk, anyone who undergoes bariatric surgery is at risk of Iron deficiency.
Because gastric bypass can affect the way your body digests and metabolizes nutrients, patients who have received the surgery need to pay close attention to their iron levels. There are several preventative measures patients can take to lower their risk of post-surgery iron deficiency and anemia.
There are many risks associated with prolonged anemia, such as fatigue, arrhythmia, heart complications, and in severe cases, death. It is highly encouraged to closely monitor iron and blood cell levels following major surgery.
Causes of Anemia after Bypass Surgery
Numerous contributing factors can result in anemia. Many types of anemia are caused by the effects of gastric bypass surgery, the most common being iron deficiency anemia.
This is caused by the changes to your digestive tract and metabolic system after surgery. Gastric bypass surgery significantly shrinks the size of the stomach and bypasses a section of the small intestine where many nutrients are absorbed.
While this limits the amount of food an individual can eat, it enables weight loss. The body is unable to adequately absorb nutrients at the same rate it could before the surgery, which is the common cause of anemia.
Ulcers and internal bleeding following surgery can also lead to iron deficiency anemia.
Who is at risk of anemia after gastric bypass surgery?
- Postmenopausal women
- Individuals with a history of iron deficiency and anemia
- Patients with blood disorders like hemophilia
- Individuals with poor dietary intake
Symptoms of Iron Deficiency
Following gastric bypass surgery, it is required to monitor yourself for any symptoms of anemia. In the weeks immediately following surgery, it will be difficult to eat high-iron foods, such as red meat. This is another reason why bariatric specific multivitamin supplements are required for life.
There are many symptoms that can indicate anemia. Some of these symptoms are mild, while others are more severe. It’s important to be on the lookout for any of these symptoms as they will vary from patient to patient.
Some symptoms include, but are not limited to:

Treating Anemia in Gastric Bypass Patients
If you have been diagnosed with anemia following gastric bypass surgery, there are several treatments available. The treatment will depend on the cause.
Iron deficiency anemia may require additional supplements, dietary changes and/or IV infusions. Your healthcare provider will order tests to determine the underlying cause.
IV infusions are likely in severe cases. Routine follow-ups are to be expected following this kind of treatment.
There are other nutritional anemias that can occur including those from folate or vitamin B12 deficiency. Both of these deficiencies can result from poor dietary intake and malabsorption after gastric bypass surgery.
In any case of deficiency, a regimen of supplements will likely be prescribed. Iron soft chews will help to replace iron levels in the body. You can also find corrective supplements like sublingual B12 and B50 complex.
